So I finished 5.1 and while it was a chapter focused on Ruka, I felt somewhat unsatisfied throughout (until the final days). The final dungeon and victory lap afterwards were great but Ruka's early mind dives felt like there was a lot of meandering. The last talk with her mom ties it all up and makes it satisfactory but I felt like I kept getting dragged along for a load of nothing before day 13 even if I enjoyed the crumbs about Ruka's past.
The end more than justifies the journey. My mind's thinking...
